Through the use of PELV circuits, protection is provided against electric shock

(protection against direct and indirect contact) according to EN 60204-1 (Elec-

trical equipment of machines, General requirements). The 24 V power supply

used in the system must meet the requirements of EN 60204-1 for DC power

supplies (Response to voltage interruptions, etc.).

 Make sure that no bridges or like that may be used wiring in parallel to safety,

for example, by using the maximum conductor cross section of 1.5 mm ² or fer-

rules with insulating collar. Use for loop of lines between adjacent devices twin

wire end ferrules.

6.2 ESD protection

At unused connectors is a danger that by ESD (electrostatic discharge) damage

to the unit or other equipment arises. Ground the equipment from the installation

and use proper ESD equipment (eg, shoes, earth straps, etc.).

6.3 Connection [X40]

The SE-Power FS Safety Module STO has a combined interface for control and

feedback on the connector [X40].

To ensure the STO "Safe Torque Off" function, the control inputs STO-A and

STO-B are on two channels to be connected in parallel wiring.

This connection may be part of an emergency stop circuit or a protective door

arrangement eg.

Example single phase servo controller SE-Power FS

If at the moment of the commissioning of the servo controller, there's not (yet) a

safety orientated connection, the servo controller

SE-Power FS with the SE-Power FS Safety Module STO can be commissioned

with a minimal wiring according figure 4 with one emergency stop switch (2).

Do the minimal wiring of the inputs STO-A/STO-B and 0V-A/0V-B for commis-

sioning such a way that they must be forcibly removed if the final safety circuit will

be done.

Note

Safety functions should never be bridged.

Commissioning

Caution

Loss of the safety function!

Lack of safety function can lead to serious irreversible injuries, such as by in-

voluntary movements of the connected actuators.

 Only operate with the safety module:

 when installed and

 if all precautions are taken.

 Validate security function for completion of commissioning.

 Incorrect wiring, using the wrong safety module or external components, what

are not selected according to safety category, lead to loss of the safety function.

 Perform a risk assessment for your application and select the wiring and the

components accordingly.

7.1 Before commissioning

Perform the following steps to prepare the commissioning:

Ensure that the safety module is installed correctly.

Check the electrical installation (cable, contact assignment

 section 6). All protective earth (PE) conductors connected?

7.2 DIP switch setting

Set the DIP switches as described in the documentation for the servo controller

SE-Power FS or the fieldbus manuals.

7.3 Parameter adjustment with the Afag SE-Power ServoCommander

When detecting a change, such as replacing a module, a not acknowledgeable

error is raised. To set the application with the servo controller in operation, the

change must be "projected". This means that the change is explicitly accepted

respectively confirmed.

The acquisition of the parameters occurs in the window Safety module of the

Afag SE-Power ServoCommander.

7.4 Functional test

Note

The STO function must be validated after installation and after changes in the

installation.

This validation must be documented by the commissioner. As an aid to commis-

sioning are examples of checklists in the document "SE-Power FS STO manual".

Operation

8.1 Obligations of the operator

The operability of the safety function must be checked at appropriate intervals. It

is the responsibility of the operator to select the type of test and the intervals

within the specified period. The test shall be performed so that the proper function

of the safety device is detected in the interaction of all components.

8.2 Maintenance and care

The safety module is maintenance-free.

Troubleshooting and Diagnostics

9.1 Status Display

Mode and faults are displayed directly on the two-color LED of the safety module.

9.2 Error Messages

The servo controller shows cyclically disturbances in the seven-segment Display

on the front panel of the servo controller.

Error messages will be with "E" (for error), a main index (xx) and a sub-index (y)

displayed, eg: E 5 1 0. Warnings have the same number, but are shown with

leading and trailing center bar, eg - 1 7 0 -.

Description

Safety module or servo controller has no operating

voltage.

The power stage in the servo controller for feeding

the motor can be active or inactive.

The power stage in the servo for feeding the motor is

shut down safely.

Description

„H": The servo controller is in "safe state".

This is not synonymous with information about the status of the safety

function STO (Safe Torque Off). This can be read only by the status LED of

the safety module.

For the "unsafe state" no special indication is provided, it will be shown the

normal status display of the servo controller.
